Technical Specifications Below are the primary physical and thermal characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 5.37 °C/W (@ 100 LFM) | | **Spring Type** | Brass (Standard) | --- ### 2. Key Features & Components #### A. pushPIN™ Attachment System This part features the ATS **pushPIN™** system, which replaces traditional thermal adhesive or screw-down methods. - **Efficiency:** Ensures high-pressure contact with the chip for better heat transfer. - **Reliability:** Uses a flexible spring mechanism to prevent damage to the PCB or the component during thermal expansion. #### B. Material and Coating - **Aluminum Construction:** Offers a lightweight solution with high thermal conductivity. - **Blue Anodized Coating:** The blue finish isn't just aesthetic; it provides surface protection against corrosion and increases emissivity for better radiative cooling. #### C. Straight Fin Design The "Straight Fin" geometry is optimized for **unidirectional airflow**. It allows air to flow through the channels with minimal pressure drop, making it ideal for server racks or enclosures with dedicated cooling fans. --- ### 3. Thermal Performance (Deg C/W) Performance varies based on the Air Velocity (Measured in Linear Feet per Minute - LFM): | Velocity (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :--- | :--- | :--- | :--- | :--- | | **Resistance (°C/W)** | 5.37 | 3.00 | 2.38 | 2.06 | 1.85 | --- ### 4.
